【问题描述】：

所以我在这个井字游戏中需要一些帮助。我几乎所有东西都能正常工作，我只需要添加一些功能。这些功能包括：1.) 允许玩家选择他们想在游戏中扮演 X 还是 O，以及 2.) 如果玩家愿意，可以选择重玩游戏。我已经很好地完成了游戏的基本机制，但我只是不知道如何将这些功能添加到代码中。我已经开始为第一个功能“奠定基础”（让玩家可以选择他们的标记）。 （老实说，过去 48 小时的期末考试让我真的厌倦了，我真的可以在这里伸出援助之手）。这是我的完整代码：

#define _CRT_SECURE_NO_WARNINGS
#pragma warning(disable : 4996)
#include <stdio.h>
 #include <conio.h>


int checkwin(char gridspace[]);
void gameboard(char gridspace[]);
int gameLoop(int choice, int player, char gridspace[], char mark);

void main(void)

char grid[10] =  '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' ;
int player = 1, victory, choice;

char mark, player1, player2;
int markchoice;
do // game loop start

    gameboard(grid); // draws the game board
    if (player % 2) // player turn conditional
    
        player = 1;
    
    else
    
        player = 2;
    
    printf("Player 1, choose which mark you would like to play as (1=X or 2=O)\n"); // asks the player to choose a mark
    scanf("%c", &markchoice);
    if (markchoice == 1) // mark choice conditional
    
        mark = 'X';            
    
    else
    
        mark = 'O';             
    
    printf("Player %d, enter the number of the place you wish to place your mark:  ", player); // asks the player to place their mark on a space
    scanf("%d", &choice);
    if (player == 1) // mark type (X or O) placement conditional 
    
        mark;
    
    else
    
        mark;
    
    gameLoop(choice, player, grid, mark); // calls the main game function that houses the conditionals 
    
    victory = checkwin(grid); // checks the state of the game (if its in progress, a draw, or a player has achieved victory.

    player++;
 while (victory == -1); //end of game loop

gameboard(grid); // redraws the game board

if (victory == 1) // conditional that breaks the game loop and gives a result (victory or draw)

    printf("==>\aPlayer %d win ", --player);

else 

    printf("==>\aGame draw");
    getch();

return 0; 
 // end of main
int gameLoop(int choice,int player, char gridspace[], char mark) // function for game loop 
decisionals

if (choice == 1 && gridspace[1] == '1')
    gridspace[1] = mark;

else if (choice == 2 && gridspace[2] == '2')
    gridspace[2] = mark;

else if (choice == 3 && gridspace[3] == '3')
    gridspace[3] = mark;

else if (choice == 4 && gridspace[4] == '4')
    gridspace[4] = mark;

    gridspace[5] = mark;

我们将不胜感激任何和所有的帮助。所以提前谢谢你！

【参考方案1】：

要允许多轮循环，您可以在游戏之外添加另一个 while 循环，以重置所有统计数据并重新开始游戏，直到玩家决定停止（您可以使用 scanf 来检查 y/n）。
